Severity: Critical
Date    : 2015-04-22
CVE-ID  : CVE-2015-2706
Package : firefox
Type    : arbitrary code execution
Remote  : Yes
Link    : https://wiki.archlinux.org/index.php/CVE

Summary
=======

The package firefox before version 37.0.2-1 is vulnerable to arbitrary
code execution.

Resolution
==========

Upgrade to 37.0.2-1.

# pacman -Syu "firefox>=37.0.2-1"

The problem has been fixed upstream in version 37.0.2.

Workaround
==========

None.

Description
===========

Mozilla developer Robert Kaiser reported that a specially crafted HTML,
when loaded by the target user, will trigger a use-after-free race
condition when a plugin fails to initialize, which may lead to a memory
corruption error in AsyncPaintWaitEvent::AsyncPaintWaitEvent() and
arbitrary code execution on the target system.

Impact
======

A remote attacker is able to use a specially crafted HTML that, when
loaded by the target user, will trigger a race condition leading to
memory corruption and arbitrary code execution.
